## PolygonsPresentation Transcript

• Polygons What are they?
• Polygons
• There are both irregular and regular polygons
• Polygons are shapes with a face, three or more sides and is a closed figure
• There are also polygons called convex and concave
• Polygons come in many different shapes
• Although polygons that are round like a circle (or polygons that do not have all straight lines) are not polygons
• Regular Polygons
• Regular polygons have equal sides and angles all the way around
Regular Triangle Irregular Polygons
• Irregular polygons have unequal sides although some irregular polygons have equal angles

• Concave Polygon
• Convex polygons are shapes that curve out of a usual shape (or just does not have a dent in it)
• Concave polygons are shapes that curve inward (if you can draw a straight line from inside one part of the shape going out of the shape then inside again to the other side, it is concave)
